Enhance your system’s e  ciency 
at a fraction of the cost
Designed to work with your present air conditioning or heat pump system, QwikSEER+ 
WattSaver™ has been demonstrated to provide EER improvements of 7-13%* along 
with improved humidity removal.
  Saves money
  Uses less energy
QwikSEER+ WattSaver’s™ plug & play design is fully compatible with your existing 
system. No need to change or purchase additional components. QwikSEER+ WattSaver™ 
handles everything automatically! 
Indoor air quality (IAQ) is a vital factor in 
maintaining a healthy life. By reducing 
the humidity in a home, mold growth is 
avoided. 
According to the EPA (http://www.epa.
gov/mold/preventionandcontrol.html), 
to prevent mold, relative humidity should 
be maintained below 60%. 
QwikSEER+ WattSaver™ has been 
shown to improve humidity removal 
rates by up to 566%. This increased 
moisture removal can signi cantly 
improve indoor comfort while also 
inhibiting the formation of mold, thus 
improving IAQ.
QwikSEER+ WattSaver’s™ optional 
humidity control is engineered to 
optimize the system for fastest humidity 
removal during high-humidity situations.

*Independent Laboratory Testing at Intertek (Plano, Texas) following ANSI/ASHRAE 37 test protocol and using a residential 14 SEER air handler and condensing unit 
(80°F indoor, 97°F outdoor temperatures) resulted in an EER improvement of 7.4%. Using the same condensing unit and temperature conditions with a residential 
furnace unit resulted in an EER improvement of 10.5%. On cooler days, (82°F outdoor temperature) the EER improvements for air conditioning and furnace units 
increased to 10.9% and 12.9% respectively. For complete test results, go to www.qwik.com.
